Letters Patent N 107,44S, dated September 20, 1870; mzfcdeted- September 10, 1ST

The Schedule referred te in these Letters Patent and making part of 'che same To all'whont it may concern Beit known that I, GEORGE D. GuAxnLnR, of West Concord, in the county of Essex and State of .Ter-

mont, have invented a new and useful Improvement.

rember, 1869, No.9(,392, and consists in an improved arrangement of the float-lever, by which the admission-passage is opened and closed,lfor adjustment for varying heights of the sap in the boilers; also, in au arrangement for attaching the regulating apparatus to the side of the boiling kettle, and connecting it with the reservoir by a flexible pipe, the connection of the flexible pipe being such that it may be readily detached, all as hereinafter more fully specified.

Figure 1 is a longitudinal sectional elevation ot' my improved sap-feeder, and a boiling-vessel to which it is attached.

Figure 2 is a plan'of a part of the doet-lever.l The tube A, which, in the aforesaid patent, was arranged for attachment to thc'wall of a reservoir or supply-tank similarly7 to the attachmentof' a faucet, is, in this case, provided with the clamping-brackets B G, and a clamping-screw, D, for attachment to the top of the boiling-vessel, and the float-leveris made in two parts, E F,the part E being hinged to the bracket B, or it may be any projection from the hottom of the tube A, and the part F being hinged to the part E, a short distance-fiom the joint of the latter, with the bracket B, and having a curved arm, Gr, rising up through a mortise in the end of E, against which a set-screw, H, is arranged, to clamp it and hold it in any desired position.

` The receiving-cap I is placed on the top ot the part E of the lever, and has a discharging-tube, K, 'attach ed for conducting the sap to the place for dropping into the vessel L.

M is the plug or stopper in the cap I for pressing y up against the month in the nozzle N, as in the arrangement in the aforesaid patent.

The tube A is connected with the reservoir by a flexible tube,- O, having a nozzle, 1, at the end, with a cock, Q, the nozzle being fitted into the tapered hole in thc end of the tube, so as to be readily engaged or disengaged, the cock' Q, being closed when it is to be disengaged. The said cock Q may be placed in a spiggot attached to the reservoir, if preferred. This arrangement admits'ot' readily moving -the apparatus from one vessel to another, as is often required.

For adjusting the apparatus, to maintain the sap higher or lower in the boiling-vessel,'the twoparts ot' the float-lever are moved toward or from each other, and held by the set-screw H and arm G, as will be clearly understood by inspection ofthe drawingV The float R is connected to the part F of the lever by :u1 adjusting-screw, S, as a further means of adjusting it relatively to the nozzle N, for varying the height of the sap.

An adjusting screw and a swiveled nut may be used in place of the arm G and set-screw H.

Having thus described my invention,

,I claim as new, and desire to lsecure by Letters Patent- 1. The combination, with the nozzle N, of' the tube A, and the oat of a float-lever made in two parts, arranged i'or adjustment substantially as specified.

The attachment of the oat to he Heat-lever by an adjusting screw, substantially as specified.

specied.

The above specification ot my invention signed by me this day oi' 1870.
